Droplet Combustion

Hi,Dear Friends: I'm now using Fluent to model the process of liquid droplets combusting in a closed cube.Kerosene spray droplets are injected into the cube,the air in it is at a temperature of 1200K to ensure the spray could be ignited.I have some difficulty setting up the combustion model.I have tried two ways: 1.In the model->species-> panel, tick 'volumeric' and 'particle surface' under 'reactions'. 2.In the define->injections-> panel,click 'combusting',and in the 'wet combustion'below, tick 'wet combustion model',fill in liquid fraction 1. The results are not satisfactory. Can you tell me which one is correct? Or there may be some other way to solve it?Thank you very much!

Dear friend: you have to gererate a PDF file for the same, that required special licence, i do not know i you have, if not i can send you the file, this file you have to feed when asked species "Non-Premixed Combustion". Once this is done then kerocen droplet property shoud be given exectly as specified by you. and then you will defiend injection, to initialise you start with the temperature as 2000 K and in the boundary condition of air defiene mass fraction as 0.23. hope this will do. good luck.
